3.5 Seating
Engine seating is integral with the double-bottom structure and has to be of suf-
ficient strength to support the weight of the engine, transmit the propeller thrust
and withstand external couples and stresses related to propeller and engine reso-
nance.
• Before any seating work can be performed, make sure the engine is aligned
with the intermediate propeller shaft.
• The longitudinal beams situated under the engine are to protrude from the
engine room bulkhead by at least half the length of the engine, and aft as far
as possible.
• The maximum allowable rake is 3 ° to the horizontal.
More details about engine seating can be found in the relevant Fitting Instruc-
tion (DG 9710) on the WinGD webpage under the following link:
